Description

For UED experiments DESY operates the ‘relativistic gun for atomic exploration (REGAE)’. REGAE generates electron pulses with an energy of 2 - 5 MeV and a charge of up to 100 fC. An additional buncher cavity allows compress these pulses to 20 fs. For diffraction experiments with solid state samples, REGAE is equipped with a crystallography goniometer and a Jungfrau 1M detector, which allowed us to perform first high quality 3D structure determinations of inorganic samples. In the next step we plan to extend these measurements to the time-domain. In parallel, we are working on the implementation micro-beam bunch train mode for measurements of biological samples.
